LlFTlNG-JACK.

SPECIFICATION forming part of Letters Patent No. 415,703, dated November26, 1889.

Application filed October 4, 1889.

. To aZZ whom it may concern.-

Be it known that I, FENELON B. BROOK,- a citizen of the United States,residing at WVashington, in the. District of Columbia, have inventedcertain new and useful Improvements in LiftingJacks' and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to lifting-jacks.

My invention is designed more particularly for use as a wagon-jack; butit is obvious that it maybe used for any purpose for which it may proveapplicable.

My improvement consists in the following construction and combination ofparts, which will first be fully described, and the points of noveltythen set forth in the claim.

Figures 1, 2, and 3 are perspective views of my improved wagon-jack inseveral positions.

A represents the longer lever of the jack. This lever is provided with aseries of rests B, designed to bear up against the axle of the wagon tobe raised.

0 represents the shorter lever of the jack.

D is the bolt or other fastening pivoting one end of lever C to thelever A, so as to swing thereon.

E is a stop-bolt located on lever A and projecting in the path of thelever C, so as to limit the upward movement thereof.

In operation the jack is operated by slip Serial No. 326,061. (Nomodel.)

ping the lower end of lever A under the wagon-axle, and pushing againstthe upper end thereof, or by raising the lever O on its pivot until itstrikes the bolt E, as shown in Fig. 3, when the axle may be raised bypulling upon the lever O. The bolt E prevents the lever C from swingingany farther upward when pulling upon it. When the wheel on the axle hascleared the ground, the lever O is allowed to fall to the ground, thelever A being held in position by pressure against its upper end untilthe lever C has assumed its position as a brace in connection withthelower end of lever A. The lever A is simply pushed forward to allow thewheel and axle to drop to the ground, or by pulling out the brace O.

I may use any form of levers. The bolt E may be upon lever C, ifdesired. Instead of bolt E, any other form of stop may be usedas a blockof wood bolted on the levers for instance.

I claim In a lifting-jack, the combination of a main lever having ashoulder or shoulders thereon, another lever or brace pivoted to themain lever at an intermediate point thereof, and a stop upon one of thelevers to limit the movement, whereby the jack may be operated by aleverage upon either lever, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
